The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a tea drying room, such as... Figure 1-4As shown, the tea drying room includes: a main body 1, which is divided into a drying chamber and an equipment room. An insulation layer 2 is installed in the drying chamber to maintain a stable temperature; a heat-conducting pipe 3, which is installed in the interlayer between the insulation layer 2 and the drying chamber to conduct residual heat for reuse; and an air duct 4, which is laid at the bottom of the drying chamber. A base plate is laid above the air duct 4, and several through holes are opened on the base plate. Air outlet pipes 5 are inserted through these through holes. The air outlet is fixedly connected to the air guide pipe 4 and is used to guide hot air into the drying chamber to dry the tea leaves; the exhaust port 6 is located at the top of the drying chamber, and an air guide shell 7 is fixedly installed on the top of the exhaust port 6. The air outlet of the air guide shell 7 is fixedly connected to the heat conduction pipe 3 through the air guide pipe 8; the placement rack 17 is set in the drying chamber and is used to place the tea leaves to be dried; the hot air supply mechanism is set in the equipment room and is used to supply hot air for drying the tea leaves to the air guide pipe 4.

[0022] In this embodiment, the main body 1 of the drying chamber divides the space into a drying room and an equipment room, achieving functional zoning and making the equipment layout more reasonable, facilitating operation and maintenance. The drying room is used to place tea leaves for drying, while the equipment room houses related equipment such as hot air supply, avoiding direct contact between the equipment and the tea leaves to prevent contamination or interference with the drying process. The insulation layer 2 is located inside the drying chamber, effectively reducing heat loss from the drying chamber to the outside. By maintaining a stable temperature inside the drying chamber, on the one hand, it can accelerate the evaporation of moisture from the tea leaves and improve drying efficiency; on the other hand, it reduces the need for continuous heat replenishment to maintain the drying temperature, reducing energy consumption and thus lowering production costs, which helps improve the economic benefits of the tea processing industry. The insulation layer is installed in the interlayer between the insulation layer and the drying chamber, and is connected to the air guide shell 7 above the exhaust port 6 through the air guide pipe 8. When the hot and humid air at the top of the drying chamber is discharged through the exhaust port 6, it first enters the air guide shell 7, and then enters the heat conduction pipe 3 through the air guide pipe 8. The heat pipe 3 absorbs the heat carried by the humid air, conducts and stores it, and then reuses the recovered heat in the drying process. This avoids the waste caused by the direct release of large amounts of heat into the atmosphere in traditional drying ovens, significantly improving heat utilization, further reducing production costs, and promoting the sustainable development of the tea processing industry. The air duct 4 is laid at the bottom of the drying chamber, and the bottom plate above it has several through holes. The air outlet duct 5 is inserted into the through holes, and its outlet end is fixedly connected to the air duct 4. The hot air generated by the hot air supply mechanism first enters the air duct 4, and then is evenly distributed into the drying chamber through the air outlet duct 5. This design allows the hot air to blow on the tea leaves from the bottom up in all directions, increasing the contact area and contact time between the tea leaves and the hot air, making the tea leaves more evenly heated, thereby accelerating the evaporation rate of the moisture inside the tea leaves. This effectively solves the problem of slow drying and low efficiency caused by uneven hot air distribution in traditional drying ovens, improves drying efficiency, shortens the tea drying cycle, and is conducive to the large-scale production and economic benefits of tea processing. The exhaust port 6 is located at the top of the drying chamber, which facilitates the timely discharge of water vapor generated during the drying process. The top air guide shell 7 collects the hot and humid air discharged from the exhaust port 6 and guides it through the air guide pipe 8 into the heat pipe 3 for heat recovery and utilization. This avoids direct heat loss, improves the overall energy utilization efficiency, and reduces the cost of tea drying. The placement rack 17 is used to orderly place the tea leaves to be dried, allowing the tea leaves to be placed in layers in the drying chamber, avoiding uneven drying caused by accumulation. At the same time, the reasonable placement rack design facilitates the circulation of hot air among the tea leaves, further improving the drying effect and efficiency, ensuring the stability of the dried tea quality, and helping to improve the overall quality of tea processed products and enhance market competitiveness. In summary, this tea drying chamber, through the coordinated work of its various parts, effectively solves the problems of low drying efficiency and insufficient heat utilization in traditional tea drying methods, bringing a more efficient, energy-saving, and stable drying solution to the tea processing industry, with significant economic benefits and sustainable development value.

[0023] In a further preferred embodiment of the present invention, the hot air supply mechanism includes: an electric heating box 9 and a fan 11 disposed in the equipment room, wherein the air outlet of the fan 11 is connected to the air inlet of the electric heating box 9 through a pipe; a plurality of electric heating tubes 10 disposed in the electric heating box 9 for heating; and a connecting pipe 15 fixedly connected to the air outlet of the electric heating box 9, wherein the air outlet of the connecting pipe 15 is fixedly connected to the air inlet of the air guide pipe 4.

[0024] In this embodiment, the fan 11 serves as a power source, drawing in outside air and delivering it to the electric heating box 9. The electric heating tube 10 is installed inside the electric heating box 9. When the air delivered by the fan 11 flows through the electric heating box 9, the electric heating tube 10 rapidly heats the air, generating high-temperature hot air. This method of generating hot air allows for precise temperature control. By adjusting the power of the electric heating tube 10 according to the different stages of tea drying, suitable hot air temperatures can be obtained, ensuring that the tea is dried in a suitable temperature environment. This improves drying quality and efficiency, and avoids adverse effects on tea quality due to excessively high or low temperatures. The combined structure of the electric heating box 9 and the fan 11 is compact and located within the equipment room. This facilitates centralized management and maintenance, and its separation from the drying chamber reduces interference from equipment operation on the tea inside the drying chamber, ensuring the stability and reliability of the drying process. The connecting pipe 15 is fixedly connected between the air outlet of the electric heating box 9 and the air inlet of the air guide pipe 4, acting as a bridge for delivering hot air. The hot air, heated by the electric heating box 9, smoothly enters the air duct 4 through the connecting pipe 15, and is then evenly distributed into the drying chamber through the air outlet duct 5, providing a stable and temperature-controlled source of hot air for tea drying. This connection method ensures the continuity and stability of the hot air supply, effectively solving the problem of low drying efficiency caused by unstable hot air supply in traditional drying methods. It further improves the drying performance and reliability of the entire tea drying room, ensuring efficient tea processing and enhancing the economic benefits and production efficiency of the tea processing industry.

[0025] In a further preferred embodiment of this utility model, a filter box 12 is provided in the equipment room, and a plurality of filter plates 13 are provided in the filter box 12 for filtering the air entering the fan 11. The air outlet of the filter box 12 is connected to the air inlet of the fan 11 through a pipe. An air inlet pipe 14 is fixedly installed at the air inlet of the filter box 12, and the air inlet end of the air inlet pipe 14 extends into the outside of the equipment room.

[0026] In this embodiment, the air inlet end of the air inlet pipe 14 extends outside the equipment room, allowing outside air to be introduced into the filter box 12. Multiple filter plates 13 installed inside the filter box 12 can perform multi-stage filtration of the air entering the fan 11. These filter plates 13 (such as dust filter plates combined with activated carbon plates) can effectively remove dust, impurities, and possible microorganisms and other pollutants from the air. First, filtering out dust and impurities prevents them from adhering to the surface of the tea leaves after entering the drying chamber with the hot air, thus avoiding affecting the appearance and hygiene quality of the tea leaves. The filtered clean air then enters the fan 11 through a pipe from the air outlet end of the filter box 12, providing a pure air source for the subsequent generation of hot air.

[0027] In a further preferred embodiment of the present invention, a rotating rod 18 is rotatably installed inside the air guide shell 7, and a fan blade 19 for accelerating exhaust is fixedly installed on the rotating rod 18. A motor 20 is fixedly installed on the top of the air guide shell 7, and the output shaft of the motor 20 is fixedly connected to the rotating rod 18 through a coupling.

[0028] In this embodiment, the motor 20 serves as the power source, and its output shaft is fixedly connected to the rotating rod 18 via a coupling, driving the rotating rod 18 to rotate within the air guide shell 7. The fan blades 19, fixedly mounted on the rotating rod 18, rotate at high speed accordingly. During the tea drying process, when the humid and hot air in the drying chamber enters the air guide shell 7 through the exhaust port 6, the rotation of the fan blades 19 accelerates the flow speed of the humid and hot air within the air guide shell 7. On one hand, this allows the humid and hot air to be transported more quickly and efficiently through the air guide pipe 8 to the heat conduction pipe 3 for heat recovery and utilization, improving the working efficiency of the heat recovery system, reducing heat loss in the exhaust stage, further enhancing the heat utilization rate of the entire drying chamber, and reducing energy consumption and production costs. On the other hand, accelerating exhaust helps to promptly remove the water vapor generated in the drying chamber, maintaining a relatively low humidity environment within the drying chamber, accelerating the diffusion of moisture from the tea leaves to the outside, thereby increasing the drying speed of the tea, shortening the drying cycle, and improving drying efficiency. This benefits tea processing enterprises by increasing production output and economic benefits.

[0029] In a further preferred embodiment of the present invention, an exhaust pipe 16 for venting and depressurizing is fixedly connected to the heat-conducting pipe 3, and an automatic exhaust valve is provided on the exhaust pipe 16.

[0030] In this embodiment, during the operation of the tea drying room, the heat pipe 3 is used to recover and conduct heat. However, due to the complexity of system operation and the influence of various factors, the air pressure inside the heat pipe 3 may fluctuate abnormally. The exhaust pipe 16 is fixedly connected to the heat pipe 3. When the pressure inside the heat pipe 3 exceeds the set threshold, the automatic exhaust valve will open and the excess gas will be discharged through the exhaust pipe 16, which plays the role of exhausting and depressurizing. This can effectively prevent the heat pipe 3 from being damaged due to excessive pressure and ensure the safety and stability of the entire heat recovery system.

[0031] In a further preferred embodiment of this utility model, the placement rack 17 has a multi-layer structure, and each layer is provided with mesh holes to allow air circulation.

[0032] In this embodiment, the placement rack 17 is designed with a multi-layer structure. This layered design greatly increases the placement area of ​​tea leaves in the drying chamber, improves the space utilization of the drying room, and enables the processing of a larger quantity of tea leaves at once, thus helping to increase the production scale and capacity of tea processing enterprises. Each layer is equipped with mesh holes, which provide channels for air circulation. After the hot air generated by the hot air supply mechanism enters the drying chamber, the hot air can freely flow between the layers of tea leaves through the mesh holes. On the one hand, this ensures that the tea leaves are in full and uniform contact with the hot air, guaranteeing that each tea leaf is dried in a suitable temperature and airflow environment, effectively avoiding local overheating or uneven drying, thereby improving the drying quality and yield of the tea leaves. On the other hand, good air circulation can accelerate the evaporation rate of moisture on the surface of the tea leaves, significantly shortening the drying time, further improving drying efficiency, and reducing energy consumption and production costs.

[0033] In a further preferred embodiment of this utility model, a thermostat 21 is provided in the equipment room to regulate the temperature of the electric heating tube 10, and both the drying chamber and the equipment room are provided with openable and closable sealed doors.

[0034] In this embodiment, the temperature controller 21 is installed in the equipment room, and together with temperature sensors and other temperature control devices installed in the drying chamber, it can monitor the temperature during the drying process in real time and form a closed-loop control circuit with the electric heating element 10. By setting a target temperature, when the temperature in the drying chamber is higher or lower than the set value, the temperature controller 21 will automatically adjust the power of the electric heating element 10. In the early stage of tea drying, when a high temperature is needed to quickly remove a large amount of moisture, the temperature controller 21 can control the electric heating element 10 to operate at full power; as the drying process progresses, the moisture content of the tea decreases, and to avoid damage to the quality of the tea caused by high temperature, the temperature controller 21 will reduce the power of the electric heating element 10 to maintain the drying temperature within a suitable range. This precise temperature control function not only ensures the quality of tea drying, allowing it to be heated evenly in a suitable temperature environment and reducing the decline in tea quality caused by temperature fluctuations, such as changes in indicators like color and spiciness, but also effectively avoids excessive energy consumption, improves energy efficiency, reduces production costs, and promotes the sustainable development of the tea processing industry; both the drying chamber and the equipment room are equipped with openable and closable sealed doors. For the drying chamber, the sealed door effectively prevents heat loss and the intrusion of cold air from the outside when closed, maintaining a stable temperature and humidity environment within the chamber. This ensures the tea drying process is undisturbed by external factors, improving drying efficiency and quality. The sealed door can be easily opened for adding or removing tea. For the equipment room, the sealed door isolates the noise and heat generated by the equipment from the external environment, while preventing dust and other impurities from entering and affecting normal equipment operation. This ensures equipment stability and reliability, reduces equipment failures and maintenance costs, and provides strong support for the continuous and efficient operation of the entire tea drying room.

[0035] In summary, the main body 1 of the drying room divides the drying chamber and equipment room into a rational layout, facilitating operation and maintenance, preventing mutual interference and contamination between equipment and tea, and ensuring the orderly progress of the drying process. The insulation layer 2 reduces heat loss, stabilizes the drying chamber temperature, accelerates the evaporation of moisture from the tea leaves, improves drying efficiency, reduces energy consumption and costs, and enhances economic benefits. Simultaneously, it ensures the stability of the dried tea quality, contributing to product quality improvement. The combined design of the air duct 4, air outlet duct 5, and bottom plate allows hot air to be evenly blown onto the tea leaves from the bottom up, increasing the contact area and time, solving the problem of uneven hot air distribution in traditional systems, accelerating the drying speed of the tea leaves, and shortening the drying time. The cycle facilitates large-scale production and increased efficiency, while ensuring uniform drying and improving tea quality. The multi-layer structure and mesh design of the placement rack 17 increase the placement area, improve space utilization, promote hot air circulation, and prevent tea from piling up and causing uneven drying, further improving drying effect and efficiency, ensuring stable tea drying quality, and enhancing the overall product quality and market competitiveness. Heat recovery and energy saving: The heat pipe 3, through its connection with the exhaust port 6, air guide shell 7, and air guide pipe 8, recovers and reuses the heat from the humid air, avoiding direct heat discharge into the atmosphere and significantly improving heat utilization and reducing production costs.
